I.e. the "systemctl stop/start systemd-networkd.service" have been replaced by "networkctl reload/reconfigure" calls instead. Due to an incompatibility with systemd v247 that change had to be reverted in the netplan.io Impish package, but going forward netplan will not be calling "systemctl stop/start systemd-networkd.service" anymore.
From a netplan POV this has already been changed upstream as part of https:/ /github. com/canonical/ netplan/ pull/200
